To test if linear model, we fit the data into a line and solve for the correlation coefficient:
The equation is
y = -1537.5x + 5466.67
and the correlation coefficient is
R² = 0.964

The model can't be exponential growth since the daily supply decreases with time. So, the data is tested if it's exponential decay. The same procedure is done the exponential equation would be linearized in the form:
y = -2816.06 lnx + 4073.57
with correlation coefficient of
R² = 0.998

Since the correlation coefficient for the exponential decay model is closer to 1, it must be the right model.

5/12 × 6/7 = 5/14 with step

shutvik [7]

Answer:

Look below

Step-by-step explanation:

First you multiply the top and bottom

5/12 x 6/7

5x6 and 12x7

you get your new fraction of 30/84

then you simplify it by 6 to get 5/14

hope this helps
